''My Best Friend's Girl'' is a 2008 romantic comedy starring Jason Biggs and Dane Cook. Dane Cook plays Tank, a cocky womanizer who is paid by recently dumped guys to take their ex-girlfriends on a date and be the biggest Jerkass possible in order to make them [the young men] look good by comparison. It works pretty well...until Tank is hired by his best friend and gets more than he bargained for.

Tropes include:
* AllGirlsWantBadBoys: Alexis does, at least.
* {{Jerkass}}: Tank raises this to an art form.
** JerkWithAHeartOfGold: Underneath his layers and layers of arrogance, Tank is really this.
* RefugeInAudacity
* VillainProtagonist: Tank.
